Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
It is necessary to know thedistance from the epicenter for at least three recording stations so, geologist could compare better and when an epicenter is created they can know which one is the farthest and which one is the closest.
Three
It is recorded from three differences because you can do two tests and they can meet at one spot but it may not be the actual epicenter. They do the third test to be ssure they have the right spot or epicenter.
A minimum of three seismic stations must compare results to locate an earthquakes epicenter.
The three stations' rings that showed the distance from the epicenter and in that area would be where the epicenter is.

The Epicenter
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
I would imagine you would need a minimum of three surrounding the epicenter in order to triangulate it.
Three
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
